I have written a book on the politics of autism policy. Building on this research, this blog offers insights, analysis, and facts about recent events. If you have advice, tips, or comments, please get in touch with me at jpitney@cmc.edu

SafeMinds, an organization dedicated to demonstrating a mercury- or vaccine-related causation of autism, probably didn’t have this outcome in mind when they funded this study. They are very invested in mercury/vaccine-autism causation. This summary of research they’ve funded through 2013 includes 55 references to mercury.

Newsweek reports that the study found some changes in the brains of monkeys receiving vaccines.

SafeMinds argues that these changes all suggest a correlation between vaccination and autism. But as Alycia Halladay, chief science officer at the Autism Science Foundation, points out, these findings do not necessarily indicate anything about autism. “There are likely many biological effects that occur in an organism after a vaccine administration, but that doesn’t always mean it will cause autism,” she says.

... Halladay commends SafeMinds for financially supporting the study, but she worries that some autism advocates may be asking the wrong questions. “I'm not saying that we need to stop funding research in the environment, because we know the environment does impact neurodevelopment,” she says. Halladay likens the challenge of disputing the claim that vaccines cause autism to “playing whack-a-mole.”

“First, the proposed association was between the MMR vaccines and autism,” she says. “Then that was disproven. Then it was the thimerosal components in vaccines; now that has been further disproven in a carefully designed animal model study that aimed to specifically examine that question. It has also been suggested that the association is because of vaccine timing, but that too has been disproven. The target always seems to be moving, and the expectation is that scientific resources will be diverted to address each new modification of this hypothesized link.”
